Gentlemen,
Thank you for your responses guys. It would seem this French Spare Bulb legislation is somewhat outdated in view of LED's and serves merely to tick a box. I'll pop down to Halfords and get a pack of cheap bulbs to satisfy any eager beaver Gendarme along with 2 x Warning Triangles, First Aid Kit and Yellow jackets. Not to mention a 'UK' sticker. Cheers, Tony
